The following two letters contain exactly the same words, but
different punctuation. Notice how the meaning is completely changed.
Better be careful when you're texting.

DEAR JOHN LETTER ONE:

Dear John:

I want a man who knows what love is all about. You are generous,
kind, thoughtful. People who are not like you admit to being useless
and inferior. You have ruined me for other men. I yearn for you. I
have no feelings whatsoever when we’re apart. I can be forever
happy–will you let me be yours? Gloria

DEAR JOHN LETTER TWO:

Dear John:

I want a man who knows what love is. All about you are generous,
kind, thoughtful people, who are not like you. Admit to being
useless and inferior. You have ruined me. For other men, I yearn.
For you, I have no feelings whatsoever. When we’re apart, I can be
forever happy. Will you let me be? Yours, Gloria

Another funny example of different meanings with different
punctuation?

An English professor wrote the words,
"A woman without her man is nothing"
on the blackboard and directed the students to punctuate it
correctly.
The men wrote: "A woman, without her man, is nothing."
The women wrote: "A woman: without her, man is nothing."
